Abstract

The absorption spectra of the radicals NH and NH2 have been observed in the flash photo­lysis of hydrogen azide in the presence of an excess of inert gas. A new complex, but slightly diffuse, absorption has been detected around 2700 Å. This spectrum shows no shift when DN3 is substituted for HN3, and it is attributed to the N3 radical. The mechanism of the hydrogen azide photolysis is discussed briefly with reference to these observations.
